  • Patent number: 8352071
    Abstract: A method and related system blend fuels and dispense a blended fuel to a vehicle at a fueling station. In one aspect, the method comprises selecting the desired proportion of at least one of the fuels available at the service station, blending that fuel with another one available, and delivering the blended fuel to the vehicle. Preferably, the first fuel is a non-renewable, petroleum based one, while the second fuel is a non-petroleum based, renewable one (such as ethanol or biodiesel).

  • Patent number: 8283484
    Abstract: In one aspect of the invention, a method recovers oil from a concentrated byproduct, such as evaporated thin stillage formed during a dry milling process used for producing ethanol. The method includes forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct. Further, the step of separating the oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil from thin stillage.

  • Patent number: 8168037
    Abstract: Methods and related systems efficiently and effectively recover a significant amount of valuable, useable oil from byproducts formed during a dry milling process used for producing ethanol. The method may include forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may include evaporating the byproduct using a multi-stage evaporator, as well as recovering the oil before the final stage of the evaporator. Further, the step of recovering oil from the concentrate may include using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil.
